Definitions
- Hydraulic fracturing has been commonly used by the oil and gas industry to stimulate production of hydrocarbon wells, such as oil and/or gas wells.
- Hydraulic fracturing sometimes called “fracing” or 'Tracking” is the process of injecting fracturing fluid, which is typically a mixture of water, sand, and chemicals, into the subsurface to fracture the subsurface geological formations and release otherwise encapsulated hydrocarbon reserves.
- the fracturing fluid is typically pumped into a wellbore at a relatively high pressure sufficient to cause fissures within the underground geological formations.
- the pressurized fracturing fluid is pressure pumped down and then out into the subsurface geological formation to fracture the underground formation.
- a fluid mixture that may include water, various chemical additives, and proppants (e.g., sand or ceramic materials) can be pumped into the underground formation to fracture and promote the extraction of the hydrocarbon reserves, such as oil and/or gas.
- the fracturing fluid may comprise a liquid petroleum gas, linear gelled water, gelled water, gelled oil, slick water, slick oil, poly emulsion, foam/emulsion, liquid carbon dioxide (CO2), nitrogen gas (N2), and/or binary fluid and acid.
- CO2 liquid carbon dioxide
- N2 nitrogen gas
- US 2003/079479 A1 discloses a trailer mounted mobile power generation system providing electrical power at locations where it is needed, either separate from or as a supplement to power from an electrical power distribution grid.
- US 2006/225402 A1 discloses an emissions control system for reducing combustion waste products emitted from a trailer-mounted mobile electrical power generation system.
- fracturing operations at well sites typically requires extensive investment in equipment, labor, and fuel.
- a typical fracturing operation uses a variety of fracturing equipment, numerous personnel to operate and maintain the fracturing equipment, relatively large amounts of fuel to power the fracturing operations, and relatively large volumes of fracturing fluids.
- planning for fracturing operations is often complex and encompasses a variety of logistical challenges that include minimizing the on-site area or "footprint" of the fracturing operations, providing adequate power and/or fuel to continuously power the fracturing operations, increasing the efficiency of the hydraulic fracturing equipment, and reducing any environmental impact resulting from fracturing operations.
- numerous innovations and improvements of existing fracturing technology are needed to address the variety of complex and logistical challenges faced in today's fracturing operations.
- a system for providing mobile electric power comprising: a gas turbine generator transport that comprises an inlet plenum and an exhaust collector and an inlet and exhaust transport coupled to the gas turbine generator transport and comprises an air inlet filter housing and an exhaust stack, wherein the inlet and exhaust transport is coupled to at least one side of the gas turbine generator transport such that the inlet plenum and the exhaust collector are not connected to the air filter housing and the exhaust stack at the top side of the gas turbine generator transport.
- transport refers to any transportation assembly, including, but not limited to, a trailer, truck, skid, and/or barge used to transport relatively heavy structures, such as fracturing equipment.
- the term "trailer” refers to a transportation assembly used to transport relatively heavy structures, such as fracturing equipment that can be attached and/or detached from a transportation vehicle used to pull or move the trailer.
- the trailer may include the mounts and manifold systems to connect the trailer to other fracturing equipment within a fracturing system or fleet.
- lay-down trailer refers to a trailer that includes two sections with different vertical heights. One of the sections or the upper section is positioned at or above the trailer axles and another section or the lower section is positioned at or below the trailer axles. In one embodiment the main trailer beams of the lay-down trailer may be resting on the ground when in operational mode and/or when uncoupled from a transportation vehicle, such as a tractor.
- gas turbine generator refers to both the gas turbine and the generator sections of a gas-turbine generator transport.
- the gas turbine generator receives hydrocarbon fuel, such as natural gas, and converts the hydrocarbon fuel into electricity.
- inlet plenum may be interchanged and generally referred to as “inlet”, “air intake,” and “intake plenum,” throughout this disclosure.
- exhaust collector may be interchanged throughout and generally referred to as “exhaust diffuser” and “exhaust plenum” throughout this disclosure.
- gas turbine inlet filter may be interchanged and generally referred to as “inlet filter” and “inlet filter assembly.”
- air inlet filter housing may also be interchanged and generally referred to as “filter housing” and “air filter assembly housing” throughout this disclosure.
- exhaust stack may also be interchanged and generally referred to as “turbine exhaust stack” throughout this disclosure.
- a mobile source of electricity may be configured to provide electric power to a variety of fracturing equipment located at the well sites.
- the mobile source of electricity may be implemented using at least two transports to reduce its "footprint" at a site.
- One transport, the power generation transport may comprise a gas turbine and generator along with ancillary equipment that supplies electric power to the well sites.
- the power generation transport may produce electric power in the ranges of about 15-35 megawatt (MW) when providing electric power to a single well site.
- a second transport, the inlet and exhaust transport may comprise one or more gas turbine inlet air filters and a gas turbine exhaust stack.
- the power generation transport and the inlet and exhaust transport may be arranged such that the inlet and exhaust are connected at the side of the gas turbine enclosure rather than through the top of the gas turbine enclosure.
- the mobile source of electricity may comprise a third supplemental transport, an auxiliary gas turbine generator transport, that provides power to ignite, start, or power on the power generation transport and/or provide ancillary power where peak electric power demand exceeds the electric power output of the gas turbine generator transport.
- the auxiliary gas turbine generator transport may comprise a smaller gas turbine generator than the one used in the power generation transport (e.g., provides about 1-8 MW of electric power).
- a fracturing pump transport that comprises a dual shaft electric motor configured to drive at least two pumps.
- the dual shaft electric motor may be an electric motor configured to operate within a desired mechanical power range, such as about 1,500 horsepower (HP) to about 10,000 HP.
- HP horsepower
- Each of the pumps may be configured to operate within a desired mechanical power range, such as about 1,500 HP to about 5,000 HP, to discharge fracturing fluid at relatively high pressures (e.g., about 10,000 pounds per square inch (PSI)).
- the pumps may be plunger-style pumps that comprise one or more plungers to generate the high-pressure fracturing fluid.
- the fracturing pump transport may mount and couple the dual shaft electric motor to the pumps using sub-assemblies that isolate and allow operators to remove the pumps and/or the dual shaft electric motor individually and without disconnecting the fracturing pump transport from the mobile fracturing system.

Description
- Hydraulic fracturing has been commonly used by the oil and gas industry to stimulate production of hydrocarbon wells, such as oil and/or gas wells. Hydraulic fracturing, sometimes called "fracing" or 'Tracking" is the process of injecting fracturing fluid, which is typically a mixture of water, sand, and chemicals, into the subsurface to fracture the subsurface geological formations and release otherwise encapsulated hydrocarbon reserves. The fracturing fluid is typically pumped into a wellbore at a relatively high pressure sufficient to cause fissures within the underground geological formations. Specifically, once inside the wellbore, the pressurized fracturing fluid is pressure pumped down and then out into the subsurface geological formation to fracture the underground formation. A fluid mixture that may include water, various chemical additives, and proppants (e.g., sand or ceramic materials) can be pumped into the underground formation to fracture and promote the extraction of the hydrocarbon reserves, such as oil and/or gas. For example, the fracturing fluid may comprise a liquid petroleum gas, linear gelled water, gelled water, gelled oil, slick water, slick oil, poly emulsion, foam/emulsion, liquid carbon dioxide (CO2), nitrogen gas (N2), and/or binary fluid and acid.
US 2003/057704 A1 discloses a mobile power generation unit.US 2003/079479 A1 discloses a trailer mounted mobile power generation system providing electrical power at locations where it is needed, either separate from or as a supplement to power from an electrical power distribution grid.US 2006/225402 A1 discloses an emissions control system for reducing combustion waste products emitted from a trailer-mounted mobile electrical power generation system. - Implementing large-scale fracturing operations at well sites typically requires extensive investment in equipment, labor, and fuel. For instance, a typical fracturing operation uses a variety of fracturing equipment, numerous personnel to operate and maintain the fracturing equipment, relatively large amounts of fuel to power the fracturing operations, and relatively large volumes of fracturing fluids. As such, planning for fracturing operations is often complex and encompasses a variety of logistical challenges that include minimizing the on-site area or "footprint" of the fracturing operations, providing adequate power and/or fuel to continuously power the fracturing operations, increasing the efficiency of the hydraulic fracturing equipment, and reducing any environmental impact resulting from fracturing operations. Thus, numerous innovations and improvements of existing fracturing technology are needed to address the variety of complex and logistical challenges faced in today's fracturing operations.

- As used herein, the term "transport" refers to any transportation assembly, including, but not limited to, a trailer, truck, skid, and/or barge used to transport relatively heavy structures, such as fracturing equipment.
- As used herein, the term "trailer" refers to a transportation assembly used to transport relatively heavy structures, such as fracturing equipment that can be attached and/or detached from a transportation vehicle used to pull or move the trailer. In one embodiment, the trailer may include the mounts and manifold systems to connect the trailer to other fracturing equipment within a fracturing system or fleet.
- As used herein, the term "lay-down trailer" refers to a trailer that includes two sections with different vertical heights. One of the sections or the upper section is positioned at or above the trailer axles and another section or the lower section is positioned at or below the trailer axles. In one embodiment the main trailer beams of the lay-down trailer may be resting on the ground when in operational mode and/or when uncoupled from a transportation vehicle, such as a tractor.
- As used herein, the term "gas turbine generator" refers to both the gas turbine and the generator sections of a gas-turbine generator transport. The gas turbine generator receives hydrocarbon fuel, such as natural gas, and converts the hydrocarbon fuel into electricity.
- As used herein, the term "inlet plenum" may be interchanged and generally referred to as "inlet", "air intake," and "intake plenum," throughout this disclosure. Additionally, the term "exhaust collector" may be interchanged throughout and generally referred to as "exhaust diffuser" and "exhaust plenum" throughout this disclosure.
- As used herein, the term "gas turbine inlet filter" may be interchanged and generally referred to as "inlet filter" and "inlet filter assembly." The term "air inlet filter housing" may also be interchanged and generally referred to as "filter housing" and "air filter assembly housing" throughout this disclosure. Furthermore, the term "exhaust stack" may also be interchanged and generally referred to as "turbine exhaust stack" throughout this disclosure.
- Various example embodiments are disclosed herein that provide mobile electric fracturing operations for one or more well sites. To provide fracturing operations, a mobile source of electricity may be configured to provide electric power to a variety of fracturing equipment located at the well sites. The mobile source of electricity may be implemented using at least two transports to reduce its "footprint" at a site. One transport, the power generation transport, may comprise a gas turbine and generator along with ancillary equipment that supplies electric power to the well sites. For example, the power generation transport may produce electric power in the ranges of about 15-35 megawatt (MW) when providing electric power to a single well site. A second transport, the inlet and exhaust transport, may comprise one or more gas turbine inlet air filters and a gas turbine exhaust stack. The power generation transport and the inlet and exhaust transport may be arranged such that the inlet and exhaust are connected at the side of the gas turbine enclosure rather than through the top of the gas turbine enclosure. In one embodiment, the mobile source of electricity may comprise a third supplemental transport, an auxiliary gas turbine generator transport, that provides power to ignite, start, or power on the power generation transport and/or provide ancillary power where peak electric power demand exceeds the electric power output of the gas turbine generator transport. The auxiliary gas turbine generator transport may comprise a smaller gas turbine generator than the one used in the power generation transport (e.g., provides about 1-8 MW of electric power).
- Also disclosed herein are various example embodiments of implementing mobile fracturing operations using a fracturing pump transport that comprises a dual shaft electric motor configured to drive at least two pumps. The dual shaft electric motor may be an electric motor configured to operate within a desired mechanical power range, such as about 1,500 horsepower (HP) to about 10,000 HP. Each of the pumps may be configured to operate within a desired mechanical power range, such as about 1,500 HP to about 5,000 HP, to discharge fracturing fluid at relatively high pressures (e.g., about 10,000 pounds per square inch (PSI)). In one embodiment, the pumps may be plunger-style pumps that comprise one or more plungers to generate the high-pressure fracturing fluid. The fracturing pump transport may mount and couple the dual shaft electric motor to the pumps using sub-assemblies that isolate and allow operators to remove the pumps and/or the dual shaft electric motor individually and without disconnecting the fracturing pump transport from the mobile fracturing system.
- The disclosure also includes various example embodiments of a control network system that monitors and controls one or more hydraulic fracturing equipment remotely. The different fracturing equipment, which include, but are not limited to, a blender, hydration unit, sand handling equipment, chemical additive system, and the mobile source of electricity, may be configured to operate remotely using a network topology, such as an Ethernet ring topology network. The control network system may remove implementing control stations located on and/or in close proximity to the fracturing equipment. Instead, a designated location, such as a data van and/or a remote location away from the vicinity of the fracturing equipment may remotely control the hydraulic fracturing equipment.

FIG. 1 is a schematic diagram an embodiment of awell site 100 that comprises awellhead 101 and amobile fracturing system 103. Generally, a mobile fracturing system 130 may perform fracturing operations to complete a well and/or transform a drilled well into a production well. For example, thewell site 100 may be a site where operators are in the process of drilling and completing a well. Operators may start the well completion process with vertical drilling, running production casing, and cementing within the wellbore. The operators may also insert a variety of downhole tools into the wellbore and/or as part of a tool string used to drill the wellbore. After the operators drill the well to a certain depth, a horizontal portion of the well may also be drilled and subsequently encased in cement. The operators may be subsequently pack the rig, and amobile fracturing system 103 may be moved onto thewell site 100 to perform fracturing operations that force relatively high pressure fracturing fluid throughwellhead 101 into subsurface geological formations to create fissures and cracks within the rock. Thefracturing system 103 may be moved off thewell site 100 once the operators complete fracturing operations. Typically, fracturing operations forwell site 100 may last several days. - To provide an environmentally cleaner and more transportable fracturing fleet, the
mobile fracturing system 103 may comprise a mobile source ofelectricity 102 configured to generate electricity by converting hydrocarbon fuel, such as natural gas, obtained from one or more other sources (e.g., a producing wellhead) atwell site 100, from a remote offsite location, and/or another relatively convenient location near the mobile source ofelectricity 102. Improving mobility of themobile fracturing system 103 may be beneficial because fracturing operations at a well site typically last for several days and the fracturing equipment is subsequently removed from the well site after completing fracturing operation. Rather than using fuel that significantly impacts air quality (e.g., diesel fuel) as a source of power and/or receiving electric power from a grid or other type of stationary power generation facility (e.g., located at the well site or offsite), themobile fracturing system 103 utilizes a mobile source ofelectricity 102 as a power source that burns cleaner while being transportable along with other fracturing equipment. The generated electricity from mobile source ofelectricity 102 may be supplied to fracturing equipment to power fracturing operations at one or more well sites. As shown inFIG. 1 , the mobile source ofelectricity 102 may be implemented using two transports in order to reduce the well site footprint and the ability for operators to move the mobile source ofelectricity 102 to different well sites and/or different fracturing jobs. Details regarding implementing the mobile source ofelectricity 102 are discussed in more detail inFIGS. 4A-6 . - The mobile source of
electricity 102 may supply electric power to fracturing equipment within themobile fracturing system 103 that may include, but are not limited to at least oneswitch gear transport 112, a plurality of drive power transports 104, at least oneauxiliary power transport 106, at least oneblender transport 110, at least onedata van 114 and a plurality of fracturing pump transports 108 that deliver fracturing fluid throughwellhead 101 to subsurface geological formations. Theswitch gear transport 112 may receive the electricity generated from the mobile source ofelectric power 102 via one or more electrical connections. In one embodiment, theswitch gear transport 112 may use 13.8 kilovolts (KV) electrical connections to receive power from the mobile source ofelectric power 102. Theswitch gear transport 112 may comprise a plurality of electrical disconnect switches, fuses, transformers, and/or circuit protectors to protect the fracturing equipment. Theswitch gear transport 112 may transfer the electricity received from the mobile source ofelectricity 102 to the drive power transports 104 and auxiliary power transports 106. - The
auxiliary power transport 106 may comprise a transformer and a control system to control, monitor, and provide power to the electrically connected fracturing equipment. In one embodiment, theauxiliary power transport 106 may receive the 13.8 KV electrical connection and step down the voltage to 4.8 KV, which is provided to other fracturing equipment, such as the fracturingpump transport 108, theblender transport 110, sand storage and conveyor, hydration equipment, chemical equipment,data van 114, lighting equipment, and any additional auxiliary equipment used for the fracturing operations. Theauxiliary power transport 106 may step down the voltage to 4.8 KV rather than other voltage levels, such as 600 V, in order to reduce cable size for the electrical connections and the amount of cabling used to connect themobile fracturing system 103. The control system may be configured to connect to a control network system such that theauxiliary power transport 106 may be monitored and/or controlled from a distant location, such as thedata van 114 or some other type of control center. - The drive power transports 104 may be configured to monitor and control one or more electrical motors located on the fracturing pump transports 108 via a plurality of connections, such as electrical connections (e.g., copper wires), fiber optics, wireless, and/or combinations thereof. The connections are omitted from
FIG. 1 for clarity of the drawing. The drive power transports 104 may be part of the control network system, where each of the drive power transports 104 comprise one or more variable frequency drives (VFDs) used to monitor and control the prime movers on the fracturing pump transports 108. The control network system may communicate with each of the drive power transports 104 to monitor and/or control each of the VFDs. The VFDs may be configured to control the speed and torque of the prime movers by varying the input frequency and voltage to the prime movers. UsingFIG. 1 as an example, each of the drive power transports 104 may be configured to drive a plurality of the fracturing pump transports 108. Other drive power transport to fracturing pump transport ratios may be used as desired. In one embodiment, the drive power transports 104 may comprise air filters and blowers that intake ambient air to cool the VFDs. Other embodiments of the drive power transports 104 may use an air conditioning units and/or water cooling to regulate the temperature of the VFDs. - The fracturing
pump transport 108 may receive the electric power received from thedrive power transport 104 to power a prime mover. The prime mover converts electric power to mechanical power for driving one or more pumps. In one embodiment, the prime mover may be a dual shaft electric motor that drives two different pumps. The fracturingpump transport 108 may be arranged such that one pump is coupled to opposite ends of the dual shaft electric motor and avoids coupling the pumps in series. By avoiding coupling the pump in series, the fracturingpump transport 108 may continue to operate when either one of the pumps fails or have been removed from the fracturingpump transport 108. Additionally, repairs to the pumps may be performed without disconnecting the system manifolds that connect the fracturingpump transport 108 to other fracturing equipment within themobile fracturing system 103 andwellhead 101. Details regarding implementing the fracturingpump transport 108 are discussed in more detail inFIGS. 7A-7B . - The
blender transport 110 may receive the electric power fed through theauxiliary power transport 106 to power a plurality of electric blenders. A plurality of prime movers may drive one or more pumps that pump source fluid and blender additives (e.g., sand) into a blending tub, mix the source fluid and blender additives together to form fracturing fluid, and discharge the fracturing fluid to the fracturingpump transport 108. In one embodiment, the electric blender may be a dual configuration blender that comprises electric motors for the rotating machinery that are located on a single transport, which is described in more detail inU.S. Patent Application Publication No. 2012/0255734, filed April 6, 2012 by Todd Coli et al. and entitled "Mobile, Modular, Electrically Powered System for use in Fracturing Underground Formations," which is herein incorporated by reference in its entirety. In another embodiment, a plurality of enclosed mixer hoppers may be used to supply the proppants and additives into a plurality of blending tubs. The electric blender that comprises the enclosed mixer hoppers are discussed in more detail inFIGS. 9A and 9B . - The
data van 114 may be part of a control network system, where thedata van 114 acts as a control center configured to monitor and provide operating instructions in order remotely operate theblender transport 110, the mobile source ofelectricity 102, and fracturingpump transport 108 and/or other fracturing equipment within themobile fracturing system 103. For example, thedata van 114 may communicate via the control network system with the VFDs located within the drive power transports 104 that operate and monitor the health of the electric motors used to drive the pumps on the fracturing pump transports 108. In one embodiment, thedata van 114 may communicate with the variety of fracturing equipment using a control network system that has a ring topology. A ring topology may reduce the amount of control cabling used for fracturing operations and increase the capacity and speed of data transfers and communication. Details regarding implementing the control network system are discussed in more detail inFIG 10 . - Other fracturing equipment shown in
FIG. 1 , such as gas conditioning transport, water tanks, chemical storage of chemical additives, hydration unit, sand conveyor, and sandbox storage are known by persons of ordinary skill in the art, and therefore are not discussed in further detail. In one or more embodiments of themobile fracturing system 103, one or more of the other fracturing equipment shown inFIG. 1 may be configured to receive power generated from the mobile source ofelectricity 102. Additionally, as shown inFIG. 1 , one or more embodiments of themobile fracturing system 103 may not include the use of a missile that receives low-pressure fluid and releases high-pressure fluid towards thewellhead 101. The control network system for themobile fracturing system 103 may remotely synchronizes and/or slaves the electric blender of theblender transport 110 with the electric motors of the fracturing pump transports 108. Unlike a conventional diesel powered blender, the electric blenders may perform rate changes to the pump rate change mounted on the fracturing pump transports 108. In other words, if the pumps within the fracturing pump transports 108 perform a rate change increase, the electric blender within ablender transport 110 may also automatically compensate its rate and ancillary equipment, such as the sand conveyor, to accommodate the rate change. Manual commands from an operator may not be used to perform the rate change. -
FIG. 2 is a schematic diagram an embodiment of awell site 200 that includes a mobile source ofelectricity 204 that comprises three transports for themobile fracturing system 202. Themobile fracturing system 202 may be substantially similar tomobile fracturing system 103, except that mobile fracturing system comprises an auxiliary gasturbine generator transport 206. The auxiliary gasturbine generator transport 206 may be configured to provide power to ignite, start, or power on the mobile source ofelectricity 204 and/or provide ancillary power where peak electric power demand exceeds the electric power output of a gas turbine generator transport. The auxiliary gas turbine generator transport may comprise a smaller, gas turbine or diesel generator that generates less power (e.g., provides about 1-8 MW of electric power) than the one used in the gas turbine generator transport. Additionally or alternatively, the auxiliary gasturbine generator transport 206 may provide testing, standby, peaking, and/or other emergency backup power functionality for themobile fracturing system 202. -
FIG. 2 illustrates that themobile fracturing system 202 arranges and positions thedrive power transport 104 and theauxiliary power transport 106 in an orientation that is about parallel to theswitch gear transport 112 and the fracturing pump transports 108. Positioning thedrive power transport 104 and theauxiliary power transport 106 in a parallel orientation rather than about a perpendicular orientation as shown inFIG. 1 may be beneficial, for example reducing the foot print of themobile fracturing system 202. Moreover,FIG. 2 also illustrates that afuel source 208, such as natural gas from a producing wellhead, may be located at the well site and be used by the mobile source ofelectricity 204 to generate electricity. - Although
FIGS. 1 and2 illustrate a specific configuration for amobile fracturing system 103 at awell site 100, the disclosure is not limited to that application and/or the specific embodiment illustrated inFIGS. 1 and2 . For instance, embodiments of the present disclosure may include a plurality ofwellheads 101, a plurality of blender transports 110, and a plurality of auxiliary power transports 106. Additionally, the mobile source ofelectricity 102 is not limited for use in a fracturing operation and may be applicable to power other types of equipment and devices not typically used in a fracturing operation. The use and discussion ofFIGS. 1 and2 is only an example to facilitate ease of description and explanation. - FIG. 3 is a schematic diagram an embodiment of a
well site 300 that includes twowellheads 101 and twodata vans 114. The twodata vans 114 may be part of the control network system that simultaneously monitors and provides operating instructions to the twodifferent wellheads 101. Anadditional blender transport 110 may be added to provide fracturing fluid to fracturing pump transports 108 used to fracture the subsurface geological structure underneath thesecond wellhead 101. Although FIG. 3 illustrates that bothwellheads 101 are located on thesame well site 300, other embodiments may have thewellheads 101 located at different well sites. - The mobile source of electricity may be part of the mobile fracturing system used at a well site as described in FIGS. 1-3. In other words, the mobile source of electricity may be configured to be transportable to different locations (e.g., different well sites) along with other fracturing equipment (e.g., fracturing pump transports) that are part of the mobile fracturing system and may not be left behind after completing fracturing operations. The mobile source of electricity may include at least two different transports that improve mobility of the dedicated electric power by simplifying and minimizing the operations for the mobilization and demobilization process. For example, the mobile source of electricity may improve mobility by enabling a mobilization and de-mobilization time period of about 24 hours. The mobile source of electricity also incorporates a two transport footprint, where the same two transport system may be used for transportation and operation modes. Although
FIGS. 4A-6 illustrate embodiments of implementing a mobile source of electricity using two different transports, other embodiments of the mobile source of electricity may mount the gas turbine generator, air inlet filter housing, gas turbine exhaust stack, and other components shown inFIGS. 4A-6 on a different number of transports (e.g., all on one transport or more than two transports). To provide electric power for fracturing operations at one or more locations (e.g., well sites), the mobile source of electricity be designed to unitize and mobilize a gas-turbine and generator adapted to convert hydrocarbon fuel, such as natural gas, into electricity. -
FIGS. 4A and 4B are schematic diagrams of an embodiment of the gasturbine generator transport 400.FIG. 4A illustrates a side-profile view of the gasturbine generator transport 400 with aturbine enclosure 402 that surrounds components within the gasturbine generator transport 400 and includes cavities for theinlet plenum 404,exhaust collector 406, and anenclosure ventilation inlet 418.FIG. 4B illustrates a side-profile view of the gasturbine generator transport 400 that depicts the components within theturbine enclosure 402. As shown inFIG. 4B , the gasturbine generator transport 400 may comprise the following equipment: (1) aninlet plenum 404; (2) a gas turbine 407 (e.g., General Electric (GE) 2500); (3) anexhaust collector 406; (4) agenerator 408; (5) agenerator breaker 410; and (6) acontrol system 412. Other components not shown inFIG. 4B , but which may also be located on the gasturbine generator transport 400 include a turbine lube oil system, a fire suppression system, and a generator lube oil system. - The gas
turbine generator transport 400 includes thegas turbine 407 to generate mechanical energy (i.e., rotation of a shaft) from a hydrocarbon fuel source, such as natural gas, liquefied natural gas, condensate, and/or other liquid fuels. As shown inFIG. 4B , the gas turbine shaft is connected to thegenerator 408 such that thegenerator 408 converts the supplied mechanical energy from the rotation of the shaft to produce electric power. Thegas turbine 407 may be a gas turbine, such as the GE LM2500 family of gas turbines, the Pratt and Whitney FT8 gas turbines, or any other gas turbine that generates enough mechanical power for agenerator 408 to power fracturing operations at one or more well sites. Thegenerator 408 may be a Brush BDAX 62-170ER generator or any other generator configured to generate electric power for fracturing operations at one or more well sites. For example, thegas turbine 407 andgenerator 408 combination within a gasturbine generator transport 400 may generate electric power from a range of at least about 15 megawatt (MW) to about 35 MW. Other types of gas-turbine generators with power ranges greater than about 35 MW or less than about 15 MW may also be used depending on the amount of power needed at the well sites. In one embodiment, to increase mobility of the gasturbine generator transport 400, thegas turbine 407 may be configured to fit within a dimension of about 14.5 feet long and about four feet in diameter and/or thegenerator 408 may be configured to fit within a dimension of about 18 feet long and about 7 feet wide. - The
generator 408 may be housed within theturbine enclosure 402 that includes air ventilation fans internal to thegenerator 408 that draws air into the air inlet located on the front and/or back of thegenerator 408 and discharges air out on the sides via theair outlets 414. Other embodiments may have the air outlets positioned on different locations of the enclosure for thegenerator 408. In one embodiment, the air inlet may be inlet louvres and the air outlets may be outlet louvres that protect the generator from the weather elements. A separate generator ventilation stack unit may be mounted on the top of the gasturbine generator transport 400. - The
turbine enclosure 402 may also comprise gas turbine inlet filter(s) configured to provide ventilation air and combustion air via one ormore inlet plenums 404 to thegas turbine 407. Additionally,enclosure ventilation inlets 418 may be added to increase the amount of ventilation air. The ventilation air may be air used to cool thegas turbine 407 and ventilate thegas turbine enclosure 402. The combustion air may be the air that is supplied to thegas turbine 407 to aid in the production of the mechanical energy. Theinlet plenum 404 may be configured to collect the intake air from the gas turbine inlet filter and supply the intake air to the gas turbine. Theexhaust collector 406 may be configured to collect the air exhaust from the gas turbine and supply the exhaust air to the gas turbine exhaust stack. - To improve mobility of the gas
turbine generator transport 400, the air inlet filter housing and the gas turbine exhaust stack are configured to be connected from at least one of the sides of theturbine enclosure 402, as opposed to connecting both the air inlet filter housing and the gas turbine exhaust stack on the top of theturbine enclosure 402 or connecting the air inlet filter housing at one end of the gasturbine generator transport 400 and connecting the exhaust collector from the side of theturbine enclosure 402. The air inlet filter housing and gas turbine exhaust stack from the inlet and exhaust transport may connect with theturbine enclosure 402 using one or more expansion connections that extend from one or both of the transports, located at the sides of theturbine enclosure 402. Any form of connection may be used that provides coupling between theturbine enclosure 402 and the air inlet filter housing and gas turbine exhaust stack without using a crane, forklift, and/or any other external mechanical means to connect the expansion connections in place and/or to connect the air inlet filter housing and gas turbine exhaust stack to the side of theturbine enclosure 402. The expansion connections may comprise a duct and/or an expansion joint to connect the air inlet filter housing and gas turbine exhaust stack to theturbine enclosure 402. Additionally, the routing of the air inlet filter housing and gas turbine exhaust stack via the sides of theturbine enclosure 402 may provide a complete aerodynamic modeling where the inlet air flow and the exhaust air flow are used to achieve the gas turbine nameplate output rating. The inlet and exhaust transport is discussed in more detail later inFIGS. 5A and 5B . - To improve mobility over a variety of roadways, the gas
turbine generator transport 400 inFIGS. 4A and 4B may have a maximum height of about 13 feet and 6 inches, a maximum width of about 8 feet and 6 inches, and a maximum length of about 66 feet. Further, the gasturbine generator transport 400 may comprise at least three axles used to support and distribute the weight on the gasturbine generator transport 400. Other embodiments of the gasturbine generator transport 400 may be transports that exceed three axles depending on the total transport weight. The dimensions and the number of axles may be adjusted to allow for the transport over roadways that typically mandate certain height, length, and weight restrictions. - In one embodiment, the
gas turbine 407 andgenerator 408 may be mounted to anengineered transport frame 416, a sub-base, sub-skid, or any other sub-structure used to support the mounting ofgas turbine 407 andgenerator 408. The single engineered transport frame may be used to align the connections between thegas turbine 407, thegenerator 408, theinlet plenum 404 and theexhaust collector 406 and/or lower the gas turbine and generator by configuring for a flush mount to the single engineeredtransport frame 416. The singleengineered transport frame 416 may allow for easier alignment and connection of thegas turbine 407 andgenerator 408 compared to using separate sub-base for thegas turbine 407 andgenerator 408. Other embodiments of the gasturbine generator transport 400 may use a plurality of sub-bases, for example, mounting thegas turbine 407 on one sub-base and mounting thegenerator 408 on another sub-base. -
FIG. 4B illustrates that thegenerator breaker 410 andcontrol systems 412 may be located on the gasturbine generator transport 400. Thegenerator breaker 410 may comprise one or more circuit breakers that are configured to protect thegenerator 408 from current and/or voltage fault conditions. Thegenerator breaker 410 may be a medium voltage (MV) circuit breaker switchboard. In one embodiment, the generator breaker may be about three panels, two for the generator and one for a feeder that protect relays on the circuit breaker. In one embodiment, thegenerator breaker 410 may be vacuum circuit breaker. Thecontrol system 412 may be configured to control, monitor, regulate, and adjust the power output of thegas turbine 407 andgenerator 408. For example, thecontrol system 412 may monitor and balance the load produced by the fracturing operations by generating enough electric power to match the load demands. Thecontrol system 412 may also be configured to synchronize and communicate with a control network system that allows a data van or other computing systems located in a remote location (e.g., off the well site) to control, monitor, regulate, and adjust power output of thegenerator 408. AlthoughFIG. 4B illustrates that thegenerator breaker 410 and/orcontrol system 412 may be mounted on the gasturbine generator transport 400, other embodiments of the mobile source of electricity may mount thegenerator breaker 410 and/orcontrol system 412 in other locations (e.g. switch gear transport). - Other equipment that may also be located on the gas
turbine generator transport 400, but are not shown inFIGS. 4A and 4B include the turbine lube oil system, gas fuel valves, generator lube oil system, and fire suppression system. The lube oil systems or consoles, which generally refer to both the turbine lube oil system and generator lube oil system within this disclosure, may be configured to provide a generator and turbine lube oil filtering and cooling systems. In one embodiment, the turbine lube oil console area of the transport may also contain the fire suppression system, which may comprise sprinklers, water mist, clean agent, foam sprinkler, carbon dioxide, and/or other equipment used to suppress a fire or provide fire protection for thegas turbine 407. The mounting of the turbine lube oil consoles and the fire suppression system onto the gasturbine generator transport 400 reduces this transport's footprint by eliminating the need for an auxiliary transport and connections for the turbine and generator lube oil, filtering, cooling systems and the fire suppression system to the gas turbine generator transport. The turbine and generator lube oil systems may be mounted on a skid that is located underneath thegenerator 408 or any other location on the gasturbine generator transport 400. -
FIGS. 5A and 5B are schematic diagrams of embodiments of an inlet andexhaust transport 500. Specifically,FIG. 5A depicts the inlet andexhaust transport 500 while in transportation mode andFIG. 5B depicts the inlet andexhaust transport 500 while in operational mode. As shown inFIGS. 5A and 5B , the inlet and exhaust transports 500 include an airinlet filter housing 502 and a gasturbine exhaust stack 504. Although not shown inFIGS. 5A and 5B , one or more gas turbine inlet filters and ventilation fans may be located within or housed in the air inlet filter housing 302. -
FIGS. 5A and 5B illustrate that the airinlet filter housing 502 may be mounted on the inlet andexhaust transport 500 at a fixed location. Other embodiments of the inlet andexhaust transport 500 may mount the airinlet filter housing 502 with a configuration such that the airinlet filter housing 502 may slide in one or more directions when transitioning between operational mode and transportation mode. For example, the airinlet filter housing 502 may slide out for operational mode and slide back for transport mode. Sliding the airinlet filter housing 502 may be used to align the airinlet filter housing 502 with the inlet plenum of the gas turbine enclosure mounted on the gas turbine generator transport. In another embodiment, the airinlet filter housing 502 may be mounted on a turntable with the ability to engage the inlet plenum of the gas turbine enclosure mounted on the gas turbine generator transport. The airinlet filter housing 502 may comprise a plurality of silencers that reduce noise. The different embodiments for mounting the airinlet filter housing 502 may depend on the amount of clean air and the air flow dynamics needed to supply the gas turbine for combustion. - The gas
turbine exhaust stack 504 may comprise thegas turbine exhaust 508, anexhaust extension 506 configured for noise control, and anexhaust end connector 510. Theexhaust extension 506 may comprise a plurality of silencers that reduce noise from the inlet andexhaust transport 500. As shown inFIG. 5A , the gasturbine exhaust stack 504 may be mounted to initially lie on its side during transportation mode. In operational mode, the gasturbine exhaust stack 504 may be rotated up without using external mechanical means such that the gasturbine exhaust stack 504 is mounted to the inlet andexhaust transport 500 on its base and in the upright position. In operational mode, the gasturbine exhaust stack 504 may be positioned using hydraulics, pneumatics, and/or electric motors such that it aligns and connects with theexhaust end connector 510 and exhaust collector of the gas turbine enclosure shown inFIGS. 4A and 4B . - The
exhaust end connector 510 may be adjusted to accommodate and align the gasturbine exhaust stack 504 with the exhaust collector of the gas turbine enclosure. In operational mode, theexhaust end connector 510 may move forward in a side direction, which is in the direction toward the gas turbine enclosure. Theexhaust end connector 510 may move backward in the side direction, which is in the direction away from the gas turbine enclosure, when transitioning to the transportation mode. Other embodiments of the gasturbine exhaust stack 504 may have thegas turbine exhaust 508 and theexhaust end connector 510 connected as a single component such that theexhaust end connector 510 and the gasturbine exhaust stack 504 are rotated together when transitioning between the transportation and operational modes. - In another embodiment, during transport, the gas
turbine exhaust stack 504 may be sectioned into a first section and a second section. For example, the first section may correspond to thegas turbine exhaust 508 and the second section may correspond to theexhaust extension 506. The first section of the gasturbine exhaust stack 508 may be in the upright position and the second section of the gasturbine exhaust stack 506 may be mounted adjacent to the first section of the gas turbine exhaust for transport. The first section and the second section may be hinged together such that the second section may be rotated up to stack on top of the first section for operation. In another embodiment, the gasturbine exhaust stack 504 may be configured such that the entire gasturbine exhaust stack 504 may be lowered or raised while mounted on the inlet andexhaust transport 500. - Typically, the air
inlet filter housing 502 and gasturbine exhaust stack 504 may be transported on separate transports and subsequently crane lifted onto the top of gas turbine enclosure and mounted on the gas turbine generator transport during operation mode. The separate transports to carry the airinlet filter housing 502 and gasturbine exhaust stack 504 may not be used during operational mode. However, by adapting the airinlet filter housing 502 and gasturbine exhaust stack 504 to be mounted on a single transport and to connect to at least one of the sides of the gas turbine enclosure mounted on the gas turbine generator transport, the inlet and exhaust transport may be positioned alongside the gas turbine generator transport and subsequently connect the air inlet and exhaust plenums for operations. The result is having a relatively quick rig-up and/or rig-down that eliminates the use of heavy lift cranes, forklifts, and/or any other external mechanical means at the operational site. -
FIG. 6 is a schematic diagram of an embodiment of the two transport mobileelectric power source 600 when in operational mode.FIG. 6 illustrates a top-down-view of the coupling between the inlet andexhaust transport 500 and thegas turbine transport 400 during operational mode. Theexhaust expansion connection 602 may move and connect (e.g., using hydraulics) to theexhaust end connector 510 without using external mechanical means in order to connect the gas turbine exhaust stack of the inlet and exhaust transport with the exhaust collector of the gas turbine generator transport. Theinlet expansion connections 604 may move and connect the air inlet filter housing of the inlet and exhaust transport and the inlet plenum of the gas turbine generator transport. The twotransports exhaust expansion connection 602 andinlet expansion connections 604 are able to connect the twotransports - In one embodiment, to adjust the positioning, alignment, and distance in order to connect the two
transports transports transport 500 into a position without attaching the twotransports FIG. 6 ) used to movetransport 400 and/ortransport 500 back and forth and/or sideways. At each outrigger and/or support feet, the hydraulic walking system may comprise a first hydraulic cylinder that lifts the transport and a second hydraulic cylinder that moves the transport in the designated orientation or direction. A hydraulic walking system on the transport increases mobility by reducing the precision needed when parking the two transports next to each other. -
FIG. 11 is a flow chart of an embodiment of amethod 1100 to provide a mobile source of electricity for fracturing operations.Method 1100 may start atblock 1102 by transporting a mobile source of electricity with other fracturing equipment to a well site that comprises a non-producing well.Method 1100 may then move to block 1104 and convert the mobile source of electricity from transportation mode to operational mode. The same transports may be used during the conversation from transportation mode to operational mode. In other words, transports are not added and/or removed when setting up the mobile source of electricity for operational mode. Additionally,method 1100 be performed without the use of a forklift, crane, and/or other external mechanical means to transition the mobile source of electricity into operational mode. The conversion process for a two transport trailer is described in more detail inFIGS. 4A-6 . -
Method 1100 may then move to block 1106 and generate electricity using the mobile source of electricity to power fracturing operations at one or more well sites. In one embodiment,method 1100 may generate electricity by converting hydrocarbon fuel into electricity using a gas turbine generator.Method 1100 may then move to block 1108 and convert the mobile source of electricity from operational mode to transportation mode. Similar to block 1104, the conversion process forblock 1108 may use the same transports without using a forklift, crane, and/or other external mechanical means to transition the mobile source of electricity back to transportation mode.Method 1100 may then move to block 1110 to remove the mobile source of electricity along with other fracturing equipment from the well site once fracturing operations are completed. -
FIGS. 7A and 7B are schematic diagrams of embodiments of a fracturingpump transport 700 powered by the mobile source of electricity as described inFIGS. 4A-6 . The fracturingpump transport 700 may include aprime mover 704 powering twoseparate pumps prime mover 704 attached to twoseparate pumps FIGS. 7A and 7B illustrates that the fracturingpump transport 700 supports a singleprime mover 704 power twoseparate pumps pump transport 700 may include a plurality ofprime movers 704 that each power thepumps - A "lay-down"
trailer 710 design may provide mobility, improved safety, and enhanced ergonomics for crew members to perform routine maintenance and operations of the pumps as the "lay-down" arrangement positions the pumps lower to the ground as the main trailer beams are resting on the ground for operational mode. As shown inFIGS. 7A and 7B , the "lay-down"trailer 710 has an upper section above the trailer axles that could hold or have mounted the fracturing pump trailer power andcontrol systems 708. The fracturing pump trailer power andcontrol system 708 may comprise one or more electric drives, transformers, controls (e.g., a programmable logic controller (PLC) located on the fracturing pump transport 700), and cables for connection to the drive power trailers and/or a separate electric pumper system. The electric drives may provide control, monitoring, and reliability functionality, such as preventing damage to a grounded or shortedprime mover 704 and/or preventing overheating of components (e.g., semiconductor chips) within the electric drives. The lower section, which may be positioned lower than the trailer axles, may hold or have mounted theprime mover 704 and thepumps - In one embodiment, the
prime mover 704 may be a dual shaft electric motor that has a shaft that protrudes on opposite sides of the electric motor. The dual shaft electric motor may be any desired type of alternating current (AC) or direct current (DC) motor. In one embodiment, the dual shaft electric motor may be an induction motor and in another embodiment the dual shaft electric motor may be a permanent magnet motor. Other embodiments of theprime mover 704 may include other electric motors that are configured to provide about 5,000 HP or more. For example, the dual shaft electric motor may deliver motor power in a range from about 1,500 HP to about 10,000 HP. Specific to some embodiments, the dual shaft electric motor may be about a 5,000 HP rated electric motor or about a 10,000 HP electric motor. Theprime mover 704 may be driven by at least one variable frequency drive that is rated to a maximum of about 5,000 HP and may receive electric power generated from the mobile source of electric power. - As shown in
FIGS. 7A and 7B , one side of theprime mover 704 drives onepump 702A and the opposite side of theprime mover 704 drives asecond pump 702B. Thepumps prime mover 704. In other words, theprime mover 704 independently drives eachpump prime mover 704, which could be a dual shaft electric motor, eliminates the use of diesel engines and transmissions. Moreover, using a dual shaft electric motor on a transport may prevent dissonance or feedback when transferring power to the pumps. In one embodiment, theprime mover 704 may be configured to deliver at least about 5,000 HP distributed between the twopumps prime mover 704, which may be a dual shaft electric motor, may provide about 2,500 HP to one of thepumps 702A and about 2,500 HP to theother pump 702B in order to deliver a total of about 5,000 HP. Other embodiments may have theprime mover 704 deliver less than 5,000 HP or more than 5,000 HP. For example, theprime mover 704 may deliver a total of about 3,000 HP by delivering about 1,500 HP to one of the pumps and about 1,500 HP to the other pump. Another example may have theprime mover 704 deliver a total of about 10,000 HP by delivering about 5,000 HP to one of thepumps 702A and about 5,000 HP to anotherpump 702B. Specifically, in one or more embodiments, theprime mover 704 may operate at HP ratings of about 3,000 HP, 3,500 HP, 4,000 HP, 4,500 HP, 5,000 HP, 5,200 HP, 5,400 HP, 6,000 HP, 7,000 HP, 8,000 HP, 9,000 HP, and/or 10,000 HP. - The fracturing
pump transport 700 may reduce the footprint of fracturing equipment on a well-site by placing twopumps pumps pumps pumps pumps prime mover 704 drives afirst pump 702A and thefirst pump 702B subsequently drives asecond pump 702B. - The
prime mover 704 and each of thepumps prime mover 704 and each of thepumps prime mover 704 andpumps pump transport 700. If theprime mover 704 needs to be replaced or removed for repair, the prime mover sub-assembly may be detached from the fracturingpump transport 700 without removing the twopumps pump transport 700, removed and replaced by anew pump 702A. If theprime mover 704 and/or thepumps prime mover 704 and/or thepumps pump pump transport 700 without removal of the other pump and/or theprime mover 704. As such, the fracturingpump transport 700 may not need to be disconnected from the manifold system and driven out of the location. Instead, replacementprime mover 704 and/or thepumps pump transport 700. - To implement the independent removal of the sub-assemblies, the two

FIGS. 8A and 8B are schematic diagrams of an embodiment of ablender transport 800 that includes anelectric blender 806.FIG. 8A illustrates a top-down view of theblender transport 800 andFIG. 8B illustrates a side-profile view of theblender transport 800. Theblender transport 800 may be powered by the mobile source of electricity as described inFIGS. 1-6 . Theelectric blender 806 may be a dual configuration blender, as described inU.S. Patent Application Publication 2012/0255734 , with a blending capacity of about 240 bpm. The dual configuration blender may comprise electric motors for all rotating machinery and may be mounted on a single transport. The dual configuration blender may have two separate blending units that are configured to be independent and redundant. For example, any one or both the blending units may receive a source fluid via inlet manifolds of the blending units. The source fluid may originate from the same source or different sources. The source fluid may subsequently be blended by any one or both of the blending tub and subsequently discharged out of any one or both outlet manifolds of the blending units. Other embodiments of theblender transport 800 may be single configuration blender that includes a single blending unit. -
FIGS. 8A and 8B illustrate a "lay-down"trailer 802 design that provides mobility and improves ergonomics for the crew members that perform routine maintenance and operations of theelectric blender 806 as the "lay-down" positions the blender tubs, pumps and piping lower to the ground level and the main trailer beams are resting on the ground for operational mode. - Similar to the "lay-down"
trailer 710, the "lay-down"trailer 802 may comprise an upper section above the trailer axles and a lower section below the trailer axles. In one embodiment, theelectric blender 806 and associated equipment on the trailer may be controlled and monitored remotely via a control system network. As shown inFIGS. 8A and 8B , ablender control system 804 that comprises a PLC, transformers and one or more variable frequency drives are mounted on upper section of theblender transport 800. To provide remote control and monitoring functions, the network may interface and communicate with the PLC (e.g., provide operating instructions), and the PLC may subsequently control one or more variable frequency drives mounted on the blender trailer to drive one or more electric motors of the blender. Operating theblender transport 800 remotely may eliminate equipment operators from being exposed to hazardous environment and avoiding potential exposure concentrated chemicals, silica dust, and rotating machinery. For example, a conventional blender transport typically includes a station for an operator to manually operate the blender. By remotely controlling using the control network andblender control system 804, the station may be removed from theblender transport 800. Recall that a data van may act as a hub to provide the remote control and monitoring functions and instructions to theblender control system 804. -
FIGS. 9A and 9B are schematic diagrams of an embodiment of ablender transport 900 that includes anelectric blender 902 withenclosed mixer hoppers 904.FIG. 9A illustrates a top-down view of theblender transport 900 andFIG. 9B illustrates a side-profile view of theblender transport 900. Theelectric blender 902 is substantially similar to theelectric blender 806 except that theelectric blender 902 usesenclosed mixer hoppers 904 to add proppants and additives to the blending tub.FIGS. 9A and 9B illustrate that theelectric blender 902 is a dual configuration blender that includes twoenclosed mixer hoppers 904 powered by two electric motors, where each of the electric motors may operate anenclosed mixer hopper 904. - Blenders that comprises open hoppers and augers typically have the proppants (e.g., sand) and/or additives exposed to the weather elements. In situations where precipitation occurs at the well site, operators may cover the open hoppers and augers with drapes, tarps, and/or other coverings to prevent the precipitation from contaminating the proppants and/or additives. The
enclosed mixer hopper 904 replaces the open hopper and augers typically included in a blender (e.g.,electric blender 806 inFIGS. 8A and 8B ) with enclosed mixer hoppers 904 (FIGS. 9A and 9B ). By replacing the open hopper and augers withenclosed mixer hoppers 904 theblender transport 900 may have the advantages of dust free volumetric proppant measurement, dust free mixing of proppant and additives, moderate the transport of proppants, perform accurate volumetric measurements, increase proppant transport efficiency with low slip, prevent proppant packing from vibration, produce a consistent volume independent of angle of repose, and meter and blend wet sand. Other advantages include the removal of gearboxes and increasing safety for operators with the enclosed drum. -
FIG. 10 is a schematic diagram of an embodiment of acontrol network system 1000 used to monitor, control, and communicate with a variety of control systems located at one or more well sites.FIG. 10 illustrates that thecontrol network system 1000 may be in a ring-topology that interconnects thecontrol center 1002, blender transports 1004,chemical additive unit 1006,hydration unit 1008, and fracturing pump transports 1012. A ring topology network may reduce the amount of control cabling used for fracturing operations and increase the capacity and speed of data transfers and communication. Additionally, the ring topology may allow for two way communication and control by thecontrol center 1002 for equipment connected to thecontrol network system 1000. For example, the control center may be able to monitor and control theother fracturing equipment 1010 andthird party equipment 1014 when added to thecontrol network system 1000, and for multiple pieces of equipment to communicate with each other. In other network topologies, such as a star or mesh topology, theother fracturing equipment 1010 andthird party equipment 1014 may be limited to one way communication where data is transmitted from thefracturing equipment 1010 and/orthird party equipment 1014 to thecontrol center 1002, but not vice versa or between different pieces of equipment. - In one embodiment, the
control network system 1000 may be a network, such as an Ethernet network that connects and communications with the individual control systems for each of the fracturing equipment. Thecontrol center 1002 may be configured to monitor, control, and provide operating instructions to the different fracturing equipment. For example, thecontrol center 1002 may communicate with the VFDs located within the drive power transports 104 that operate and monitor the health of the electric motors used to drive the pumps on the fracturing pump transports 108. In one embodiment, thecontrol center 1002 may be one or more data vans. More data vans may be used when the fracturing operations include fracturing more than two wellheads simultaneously. - At least one embodiment is disclosed and variations, combinations, and/or modifications of the embodiment(s) and/or features of the embodiment(s) made by a person having ordinary skill in the art are within the teaching of the disclosure.
